MongoDB Vs. PostgreSQL: What Are the Similarities and Differences?

sql programmingThere are several software programs used in handling databases, with MongoDB and PostgreSQL being among the most popular choices. While there are a few similarities between the two software programs, there are differences in the way they are used. MongoDB vs. PostgreSQL is an interesting debate for organizations looking for the best database management system. In this post, we will compare MongoDB and PostgreSQL in a comprehensive manner.

Definitions

MongoDB is an open-source software that is used for non-relational database management systems. It is a no-schema, NoSQL, JSON database. PostgreSQL is a traditional relational database management system. Since it is basically used to manage relational databases, it is object-oriented in nature.

Are There Similarities Between MongoDB and PostgreSQL?

MongoDB and PostgreSQL are software programs that come from MongoDB Inc and PostgreSQL Development group, respectively. They are both great database management systems from two different technology giants. They actually represent two factions in the database world, which is why many choose to compare and contrast them. They are only similar in the sense that they are both computer programs used for database management.

What Are the Key Differences Between MongoDB and PostgreSQL?

The primary difference between MongoDB and PostgreSQL is that while MongoDB is an open-source non-relational database management system, PostgreSQL is a relational database management system. The other key differences you need to know about include:

  • Data in MongoDB are stored like documents and represented in a binary form (binary JSON). PostgreSQL, on the other hand, stores the data in tables, using dynamic and static schemas.
  • Monochrome follows what is referred to as distributed architecture, while PostgreSQL follows what is referred to as monolithic architecture.
  • MongoDB is mainly programmed in C and C++ programming language, as well as JavaScript language. On the other hand, PostgreSQL is mainly programmed in C language only.
  • MongoDB can be described as document-oriented because the data are handled as individual documents, which can be part of a document cluster typically referred to as a collection. PostgreSQL, on the other hand, is mainly object-oriented, handling data in a tabular form.
  • When a new column is added in MongoDB, it is referred to as a field, but in PostgreSQL, it is referred to as a column.
  • In MongoDB, the document is used for getting any information, while in PostgreSQL, the row is used.
  • MongoDB is available in only English language, which is a major problem for users who do not know the language too well. PostgreSQL, on the other hand, is available in multiple languages. This explains why it is one of the most popular relational database management systems.
  • In MongoDB, aggregation pipeline is used in queries, but PostgreSQL uses GROUP_BY for that.
  • MongoDB supports many platforms, but PostgreSQL only supports Unix-like and Windows platforms.
  • Syntax in PostgreSQL is like other relational databases, but in MongoDB, it is quite different from other relational databases.

PostgreSQL remains the ideal DBMS for businesses and organizations that deal with complex procedures, intricate designs, integration, and data integration. Conversely, MongoDB is the popular choice of database in the development industry. It is often used as a document database.
